Abstract
The present invention provides a small, thin, and cheap foldable broadband antenna that is valid in a wide band and, moreover, can be manufactured at low cost, and a method of using the same. A foldable broadband antenna includes: a plate conductor having a rectangular outer shape and in which a slit is formed from a long side so as be orthogonal to a longitudinal direction; a side conductor provided perpendicularly from a side parallel with the slit in the plate conductor; and a back conductor disposed in parallel with the plate conductor from an end of the side conductor toward the slit. In the plate conductor, a coaxial external conductor of a coaxial cable is connected to the side opposite to the side conductor with the slit therebetween, and a coaxial central conductor of the coaxial cable is electrically connected to the same side as that of the side conductor.
